解决gradle下载jar包超时问题_gradle下载jar包失败

报错情况

原始 init.gradle 配置

allprojects{
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/repository/jcenter/' }
        maven { url 'https://maven.aliyun.com/repository/central/' }
        maven { url 'https://maven.aliyun.com/repository/google/' }
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin/' }
    }
}

解决方案

Maven 公共制品库在海外，虽然配置了使用阿里云镜像，但拉取 jar 包还是查了海外资源，因此修改一下配置：

def repoConfig = {
    all { ArtifactRepository repo ->
        if (repo instanceof MavenArtifactRepository) {
            def url = repo.url.toString()
            if (url.contains('repo1.maven.org/maven2')
            	|| url.contains('repo.maven.org/maven2')
            	|| url.contains('repo.maven.apache.org/maven2')
                || url.contains('jcenter.bintray.com')
                || url.contains('maven.google.com')
                || url.contains('plugins.gradle.org/m2')
                || url.contains('repo.spring.io/libs-milestone')
                || url.contains('repo.spring.io/plugins-release')
                || url.contains('repo.grails.org/grails/core')
                || url.contains('repository.apache.org/snapshots')
            ) {
                println "gradle init: [buildscript.repositories] (${repo.name}: ${repo.url}) removed"
                remove repo
            }
        }
    }
 
    // Maven 镜像聚合了：central、jcenter、google、gradle-plugin
    maven { url 'https://maven.aliyun.com/repository/central' }
    maven { url 'https://maven.aliyun.com/repository/jcenter' }
    maven { url 'https://maven.aliyun.com/repository/google' }
    maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
    maven { url 'https://maven.aliyun.com/repository/public/' }
}
 
allprojects {
    buildscript {
        repositories repoConfig
    }
    repositories repoConfig
}

注意事项

1. maven { url ‘https://maven.aliyun.com/repository/central’ } 一定要放到第一个，有依赖顺序。
2. setting.gradle 和 build.gradle 中的 repositories 也要配置成 maven { url ‘https://maven.aliyun.com/repository/gradle-plugin’ }，以替换官方避免超时。
3. setting.gradle 中的 pluginManagement 加上如下：

repositories {
        maven {
            url 'https://maven.aliyun.com/repository/gradle-plugin'
        }
}

4. gradle-wrapper.properties 配置要使用国内地址代替官方地址去下载 gradle，否则也会超时。
